The Second Chengdu–Chongqing high-speed railway (Chinese: 成渝中线高铁; lit.
'Chengdu–Chongqing Central line high-speed railway') is a 292-kilometre (181 mi)[1] long high-speed rail line that connects the cities of Chengdu (in Sichuan Province) and Chongqing in southwestern China, with a maximum speed of 350 km/h (220 mph) and a future design speed of 400 km/h (250 mph).
The 292 kilometres (181 mi) long Second Chengdu–Chongqing high-speed railway will take a more direct route than the existing 307 kilometres (191 mi) long high-speed Chengdu–Chongqing intercity railway and is expected to reduce journey times between the two cities to 50 minutes.
[4] In addition, the section between Jianzhou and Dazu Shike will be designed for 400 km/h (250 mph) operations in the future,[5] creating potential conditions for further reductions to travel time.
Approval for the 69.273 billion yuan project was granted on August 17, 2021 by the National Development and Reform Commission.
